Ubuntu 20.04 DNS issues/questions


Fresh install of the above OS, I'm having some DNS issues, specifically with google login pages.

Figured out that it is a DNS issue on this laptop.

Code:
$ systemd-resolve --status
Global
       LLMNR setting: no                  
MulticastDNS setting: no                  
  DNSOverTLS setting: no                  
      DNSSEC setting: no                  
    DNSSEC supported: no                  
          DNS Domain: localdomain         
          DNSSEC NTA: 10.in-addr.arpa     
                      16.172.in-addr.arpa 
                      168.192.in-addr.arpa
                      17.172.in-addr.arpa 
                      18.172.in-addr.arpa 
                      19.172.in-addr.arpa 
                      20.172.in-addr.arpa 
                      21.172.in-addr.arpa 
                      22.172.in-addr.arpa 
                      23.172.in-addr.arpa 
                      24.172.in-addr.arpa 
                      25.172.in-addr.arpa 
                      26.172.in-addr.arpa 
                      27.172.in-addr.arpa 
                      28.172.in-addr.arpa 
                      29.172.in-addr.arpa 
                      30.172.in-addr.arpa 
                      31.172.in-addr.arpa 
                      corp                
                      d.f.ip6.arpa        
                      home                
                      internal            
                      intranet            
                      lan                 
                      local               
                      private             
                      test

                      localdomain
But when I use the GUI to look at the wifi settings, it reflects correctly to my internal Pi-Hole DNS server IP: 192.168.0.16

There are no other devices in the network providing DNS, specifically the 192.168.1.10 IP

question, am I reading the above code correct that it is saying my current DNS provider is on an IP scheme I am not connected with?

If I am reading that correct, how to fix Ubuntu as the standard practice for editing /etc/resolv.conf is a no go in Ubuntu. Bad on Ubuntu.

so goofed on my copy/paste.

Anyone else out there having DNS issues using either OpenDNS or CloudFairs DNS servers and getting the google login pages to work?

Hm. I see that systemd-resolve reports the same DNS server as your GUI. You say that this is correct. What is your question?
